INITIAL LIGHTING DEVICE FOR GASOLINE-VAPOR STOVES.

SPECIFICATION forming part of Letters Patent No. 398,691, dated February 26, 1889.

Application filed January 24, 1889. Serial No. 297,467. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. BILLINGs, of Cleveland, in the county of (luyahoga and State of Ohio, have invented new and Improved Initial Lighting Devices for Gasoline- Vapor Stoves; and I do hereby declare that the following is a full, true, and exact description thereof.

My invention consists of devicesarranged for the initial lighting for heating of the 1 v l above the surface of the necessary quantity generators of vapor-lmrners, by which means the fluid is burned without smoke, thus avoiding the accumulation of soot on the burner and other parts or articles about the stove brought in contact with the smoke.

That the device may be fully understood, reference will be had to the annexed specification and the accompanying drawings, in which Figure 1 is a vertical side elevation of a burner and a section through the stand-pipe and initial lighting device on line a? at, 2. Fig. 2 is a plan view of the initial lighting device havin the stand-pipe inserted but detaehed from the burner. 1

Like letters Of reference denote like parts in the drawings and speciiicaiionr In Fig. I A represents the stand-pipe, to which is attached the vapor-burner B.

C is the inlet-tube, and I) the needlevalve thereof.

E is the deflector, which for support has its arm F pivoted to the side of the needle valve I). (This pivotal connection is not shown in the drawings.) Said deflector can be swung so as to be just in front of the needle-valve D, as indicated in Fig. l, or moved to the side thereof, when a free passage from the needle-valves to the comhustion-chanr ber of the burners ensues.

As shown, the deflector is set or swung between the needle-valve and the inlet-tube C, in which case the discharge from the needlevalve is deflected from a straight course to that indicated by the arrow 1, which leads to the initial lighting device underneath, which consists of the duplex drip-cups G and H, which are held united and set in communication with each other by means of the tubular arm a. The cup H is provided with a sleeve, 1), fitted over the stand-pipe A and held secured thereto by the set-screw I, which screw also allows of adjustment of the cups upon the stand-pipe A, as required. The fluid passes from the cups into the gage c, and indicates the quantity of gasoline in the cups, which gage is arranged at a corresponding height to till the cups sufliciently for a proper initial heating of the vapor-generators. Both the cups have perforations d and e leading to the interior on a line little of fluid, as seen in Fig. 1. In addition to that, the central part of the cup G is formed into a tubular projcctioinf, with perforations in the circumference thereof to admit air to the burning gasoline from the inside as well as from the exterior sides.

The upper part of the cup G is provided with a platform or receiver, g, as seenv in Figs. 1 and 2, into which the gasoline is conducted by the deflector E. At one side of this receiver the conduit of the arm a, leading to the cup ll, and directly opposite is the dam 71, facing the cup G, as seen in Fig. 1. This receiver 9 is arranged for filling the cups G and H with fluid received from the needle-valve. The dam It causes the cup ll to be filled Iii-st, and is arranged in such relation to the cup H as to assure a proper filling of said cup before the liquid will flow over the dam 72 down into the cup Gthat is, the edge of the dam 71 is extended up from the receiver g, so as to be little below the horizontal plane of the lower end of the perforations e, which prevents an overfilling of the cup H by enabling the continued stream of the fluid from the needle-valve to overflow into the cup G. As aforesaid, the level of the fl uidin the cup G is indicatedby its reception in the gage c. The liquid when thus appearing in said gage gives notice to shut the needle-valve before it would run out through the perforations (I. By. these means and with little care the cups G H can always be filled a certain quantity to assure a proper heating of the generators, and yet guard against overiilling or spilling of the gasoline.

The cups G and U will produce the same described results when made in one piece equally well as when made in sections. (Shown in Figs. 2 and The latter construction and arrangement, however, are preferred, in View of the means which admit of an easy separation of the parts for cleaning and removal of the sediment, which may accumulate within cups while in practical operation, and of a ready readjustment thereof.

The gasoline is ignited at the receiver g, from which the flames will soon extend to the cups G II and burn or consume the liquid therein without smoke, which is essential and an important feature in vapor-stoves, espeeially for domestic use. This is accomplished owing to the presence of the perforations through said cups directly above the surface of the fluid, which in that instance is resultantin the admission of air, thus causing the vapor, which is rapidly generated, to ignite above the fluid, and as the flame rises the entire combustion thereof is completed by the air above. The specific gravity of the vapor being comparatively so great, this procees isnot rapid, thus enabling oxygen to mix in, sufficient quantity with the vapor to produce the desired resultthatis, a smokeless flame. The con fined space in which combustion takes place will not fully admit of the surrounding atmosphere to come in contact with it, suppressing to some extent the process of combustion, so that the small amount of inflammable gas eliminated is readily and entirely consumed without smoke.

The combustion can be promoted or reduced by increasing or decreasing the depth of the cups, and also by the size of the openings leading to the interior of the cups. To suppress the proeess of combustion sufficiently that the vapor can take in enough oxygen to produce a blue flame is an object of this invention. In the confined space of the cups combustion cannot take place on the surface of the fluid, but the flame is carried above it, resultingin the entire combustion of the vapor and gas in the confined space aforesaid and on account of the depth of the cup. By this arrangement a sufficient amount of air is ad mitted to produce combustion without smoke.

This result is determined by actual tests, whereby I find that a slight variation in the depth of the cup will not change the result, which consists in producing a blue flame by the means before described.

In vapor-burners provided with an ordinary drip-cup the smoke which issues from the burning gasoline covers up with soot more or less all parts which are within its influence about the stove, and the soot soon accumulates, so as to depreciate the appearance of .the stove and is annoying to the operator while cooking.

What I claim, and desire to secure by Let ters Patent, is

1. As an improvement in vapor-stoves, the combination of the vapor-burner thereof with initial lighting devices having one or more cups provided with openings or perforations in their sides located above the surface of the gasoline, substantially and for the purpose set forth.

2. In combination with a vapor-burner, the duplex cups G H, the receiver g, the dam h,

separating said receiver from the cup G, and" a passage, (1, to the cup H, substantially as described.

23. In combination with avapor-burner, initial lighting devices consisting of two cups, one of said cups being provided with a tube, f, in the center, said tube having an open bottom and a perforated upper portion, substantially as described.

4. In combination with a vapor-burner, the duplex cups H and G, secured to the standpipeof said burner, said cup G consisting of sections, the lower section having perforations (Z in the sides and atubular projection, f, and an adjustable connection between the upper and lower sections, substantially as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
